TERM DEFINITION
bridge An OSI layer 2 networking device that connects two LANs using similar
protocols. It filters frames based on the MAC address to reduce the
amount of traffic. A bridge can be placed between two groups of hosts
that communicate a lot together, but not so much with the hosts in the
other group. The bridge examines the destination of each packet to
determine whether to transmit it to the other side. See also switch.
broadband
High bandwidth network technology that multiplexes multiple,
independent carriers to carry voice, video, data, and other interactive
services over a single cable. A communications medium that can
transmit a relatively large amount of data in a given time period. A
frequently used synonym for cable TV that can describe any technology
capable of delivering multiple channels and services.
broadcast Simultaneous transmission to multiple network devices; a protocol
mechanism supporting group and universal addressing. See also
multicast and unicast.
C
CableHome A project of CableLabs and technology suppliers to develop interface
specifications for extending high-quality, cable-based services to home
network devices. It addresses issues such as device interoperability,
QoS, and network management. CableHome will enable cable service
providers to offer more services over HFC. It will improve consumer
convenience by providing cable-delivered services throughout the
home.
CableLabs
A research consortium that defines the interface requirements for
cable modems and acknowledges that tested equipment complies with
DOCSIS.
cable modem A device installed at a subscriber location to provide data
communications over an HFC network. Unless otherwise specified, all
references to “cable modem” in this documentation refer to DOCSIS
or Euro-DOCSIS cable modems only.
cable modem
configuration file File containing operational parameters that a cable modem or gateway
downloads from the Internet Service provider TFTP server during

Class C network An IP network containing up to 253 hosts. Class C IP addresses are in
the form “network.network. network. host.”
